Introduction:
Virgin PTFE sheet, frequently misidentified as Teflon sheet, is a high performance thermoplastic with a very low moisture absorption rate, an incredibly low coefficient of friction, and good dielectric strength.
PTFE sheet is made of a fluoropolymer with low friction and exceptional chemical and weather resistance.
PTFE sheets are available in various sizes and thicknesses ranging from 6 to 150 mm. For thickness smaller than 6 mm, we direct you to choose PTFE film/foil. PTFE sheet is available from stock in standard size 1200x1200 mm, in diverse thicknesses. Other sizes are available on request. If the PTFE sheet needs to be bonded, we advise one side etched (or two side etched) PTFE sheet.
Product application:
Properties of PTFE sheets can be improved by adding additives as carbon, graphite, glass etc.
PTFE sheet gasket material comes in several forms. The first thing that must be determined is what type of PTFE gasket material you are looking for. The first and most common form is a virgin PTFE gasket material. Virgin PTFE is specified for medical or electrical applications. Most applications however are not medical or electrical and can easily be satisfied with mechanical grade PTFE.
Mechanical grade PTFE sheets are almost identical to Virgin and to the naked eye is very hard to differentiate. The difference is in mechanical grade reprocessed PTFE has been added. Generally, a very small percentage of the material is reprocessed. The percentage will vary however by the manufacturer.
